Today I came up with two other possible objectives to tackle, so instead of re-re-re-re-rereading the above, they are: BANG mode - there are certain cases where it it known that the bandwidth is going to drop significantly (examples include a cnwave to 5ghz backup transition and Starlinks’15s update cycle) where it makes sense to drop a bunch of packets immediately rather than wait for the shift to gradually be seen. tc qdisc change dev eth0 root cake bandwidth <newbandwidth> bang Cake-autorate rework - the first attempt at doing this directly in cake frankly… does not work well. There has been a lot of innovation in the sqm-autorate and cake-autorate projects, which live in userspace today that might be applied more directly. BANG mode, above, is an untried inspiration to cake autorate, and would also cope with L4S flows by doing drops on big rate changes, rather than marks. -- Oct 30: https://netdevconf.info/0x17/news/the-maestro-and-the-music-bof.html Dave Täht CSO, LibreQos _______________________________________________ Cake mailing list Cake@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/cake
